Software Product Description

UltraDefrag is a powerful, open source defragmentation tool for Windows. It's engine is very fast, because it is created as a kernel-mode driver.

There are three interfaces to them: graphical, console and native. The first is very useful, because it uses cluster map visualization. Console is good for task scheduler, and native tool - for advanced users and programmers.

UltraDefrag's design is very ergonomic: no skins, no localization, no animation and so on. It's a truely small and powerful program!


  • very fast defragmentation, because engine is kernel mode driver and has optimal algorithm.
  • very small engine written in pure C language.
  • nice graphical interface - compact and comfortable.
  • safety, because file moving is realized with special system calls.
  • simple to use.
  • generate html reports.
  • has useful filters.
  • free: distributed with full source code under the GNU General Public License.
